Flopped Nut Straight

[Soul Daddy]

It's very early in the tourney. I've been super tight so far, MP3 has played in his share of hands, hasn't shown down.

What are your thoughts on the flop bet? What's the proper price to make them pay for the next card? Should I be pushing this? And what hands are calling this raise?
